Risk assessment and resistance inheritance of triflumezopyrim resistance in Laodelphax striatellus

Pest Management Science, 2022
AbstractBACKGROUNDLaodelphax striatellus (Fallén) (Hemiptera: Delphacidae) is one of the most important insect pests of rice, and it has been able to develop strong resistance to many insecticides. Triflumezopyrim, a new type of mesoionic insecticide developed by Corteva Agriscience, showed high biological activity in controlling piercing‐sucking ...

Risk of resistance and the metabolic resistance mechanism of Laodelphax striatellus (Fallén) to cyantraniliprole

Pesticide Biochemistry and Physiology, 2023
Cyantraniliprole is a highly effective diamide insecticide used to control of Laodelphax striatellus (Fallén). This study aimed to assess the insecticide resistance risk of L. striatellus and its metabolic resistance mechanisms. After 25 continuous generations of selection, the resistance of L.

Imidacloprid is hydroxylated by Laodelphax striatellus CYP6AY3v2

Insect Molecular Biology, 2017
Abstract Laodelphax striatellus (Fallén) is one of the most destructive pests of rice, and has developed high resistance to imidacloprid. Our previous work indicated a strong association between imidacloprid resistance and the overexpression of a cytochrome P450 gene ...

Wolbachia localization during Laodelphax striatellus embryogenesis

Journal of Insect Physiology, 2019
Wolbachia are intracellular bacteria carried by thousands of arthropod species. The success of Wolbachia is due to efficient vertical transmission by the host maternal germline. Wolbachia's behavior during host oogenesis is well characterized, although their behavior during embryogenesis is unclear. Vertical transmission of Wolbachia wStri in the small

Life history responses of the small brown planthopper Laodelphax striatellus to temperature change

Journal of Thermal Biology, 2023
Temperature is a key environmental factor in ectotherms and influences many life history traits. In the present study, the nymphal development time, sex ratio and wing dimorphism of the small brown planthopper Laodelphax striatellus were examined under the conditions of constant temperatures, naturally varying temperatures (or different generations ...

The small brown planthopper ( Laodelphax striatellus ) as a vector of the rice stripe virus

Archives of Insect Biochemistry and Physiology, 2022
Abstract The small brown planthopper, Laodelphax striatellus , is a destructive pest insect found in rice fields. L. striatellus not only directly feeds on the phloem sap of rice but also transmits various viruses, such as rice stripe ...

A cytorhabdovirus-based expression vector in Nilaparvata lugens, Laodelphax striatellus, and Sogatella furcifera

Insect Biochemistry and Molecular Biology, 2022
The brown planthopper (BPH, Nilaparvata lugens), the small brown planthopper (SBPH, Laodelphax striatellus), and the white-backed planthopper (WBPH, Sogatella furcifera) are problematic insect pests and cause severe yield losses through phloem sap-sucking and virus transmission.

Roles of LsCYP4DE1 in wheat adaptation and ethiprole tolerance in Laodelphax striatellus

Insect Biochemistry and Molecular Biology, 2018
The cytochrome P450 monooxygenase (P450) gene family has an important role in detoxifying host plant allelochemicals and pesticides. In this study, we screened differentially expressed genes of the small brown planthopper (Laodelphax striatellus, SBPHs) that were reared for more than ten generations on rice and wheat plants, and found that only a few ...

Mechanism of Fipronil Resistance in Laodelphax striatellus (Hemiptera: Delphacidae)

Journal of Entomological Science, 2014
Abstract The WX-F strain of Laodelphax striatellus (Fallen) (Hemiptera: Delphacidae) was derived from a field-collected strain (WX strain) after 77 generations of continuous selection with fipronil. The selection resulted in 86.6-fold resistance to fipronil; WX-F showed no cross-resistance to dieldrin (1.8-fold) and low-level cross-resistance to ...
